Which of the following statements about benzene is true? Multiple Choice
fenix001 [56]

Answer: option a and d

Explanation:

Option A- Benzene undergoes substitution reaction

Example : benzene reacts with chlorine to form chlorobenzene, in the presence of Iron

(iii) chloride as a catalyst

C6H6 + Cl2 ---> C6H5Cl + HCl

Option D- Benzene also undergoes addition reaction

Example: benzene reacts with hydrogen , in the presence of nickel as a catalyst to form

cyclohexane

C6H6 + 3H2 ---> C6H12

Reasons why Option B isn't the answer

Although benzeme has degree of unsaturation but it's not five degree of unsaturation.

Benzene has 6 carbon atoms and 4 degrees of unsaturation (1 ring and 3 double

bonds).

If you work backwards and double the degrees of unsaturation you have 8 degrees of

unsaturation instead of 5.

Option C - Benzene isn't a saturated hydrocarbon

nata0808 [166]
<span>Uranium-236 is intermediate nuclei. created by fusion reactions an unstable isotope of uranium created from four hydrogen atoms used in the H-bomb.

Following is the reaction involved in above process:

</span>^{235}U+ ^{1}n →  ^{236}U→ ^{144}Ba + ^{89}Kr + 3 ^{1}n<span> + 177 MeV
</span>
Here, 
^{235}U = Fission material,
^{1}n = projectile,
^{236}U = intermediate nuclei,
^{144}Ba and ^{89}Kr = Fission product
